CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 376,077, dated January10, 1888.

' Application filed August 30, 1887. Serial No. 248,282. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL DAVIS, of Montreal, Province of Quebec,Canada, have invented an Improvement in Oar-Trucks, of

which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts,

This invention has for its object to prevent the trucks slewing orturning to a greater extent than demanded by the maximum curvature ofthe track, so that in case of derailment the truck will be kept underthe car in running position.

In this my invention the car-truck, near its end, is joined to the underside of the carbody by pieces of wire rope extended longitudinally ofthe car, the, combination of the parts and their construction andoperation being such asto permit the car-truck to turn under thecar-body sufliciently to enable the truck to slew or turn for themaximum curve in the track, and thereafter serve as stops or checks toany further turning.

By the employment of a wire rope having flexibility instead of a rod,which has heretofore been used, I am enabled to secure greater strengthin the connections, and at the same time have connections less liable tobe bent or wrenched asunder by a blow or sudden strain. I have alsoprovided the truck and car with a set of auxiliary conneetions,whichsupplement the action of the main connections, when, for instance, awheel meets a I sleeper, or some other obstruction on the track.

I Figure 1 is an under side view of a sufficient portion of arailway-car to enable my improvements to be understood; Fig. 2, a sideelevation of a portion of the car shown in Fig. 1, and Fig. 3 a detailto bereferred to. The car-body A, truck B, pivoted at G and havingwheels D, are and may be all as usual. The truckhas bolted to it at 'ornear its 5 corners brackets or stands at, having strong bolts a, withwhich is engagedone end of each of the connections a made of strong wirerope or cable, the opposite ends of the said connections, as hereinshown, being exo tended through or suitably attached to a slottedmetallic loop or eye, as e fitted to slide to a limited extent on astrong bolt, a, extended through the ears of a stand, a bolted to theframe-work of thecar-body, the length of the slot in the loop or eyeforming a part of the wire rope being sufficient to permit the truck toturn under the car-body to accommodate the truck to the maximumcurvature of the track on which the truck is to run.

In case of an obstruction on the track, or the derailment of the truck,or the striking of a wheel against a tie, the longitudinallyarrangedconnections between the car-body and truck prevent the latter slewingabout, and as the truck cannot slew it must keep its leading end forwardin running position.

The blow of the wheel of a rapidly-running car against an obstruction ona track or against a tie is very great; so to afford addltional securityand safety I have added to the car an auxiliary set of connections, asI), also preferably made of Wire rope, so constructed or attached atopposite ends to the car-body and truck as to permit the truck to turnunder the car-body for a determined distance, and then act as stops toany further turning of the truck.

Theauxiliary connections 12 are joined to the stands I) b ,or boltsthereon attached, respectively, to the truck and car-body.

I claim-- 1. The car-body, the stands a containing bolts a and attachedto the car-body near its sides, the truck and its attached stands a andbolts a, combined with the slotted metallic loops or eyes a and with thetwo independent longitudinally arranged flexible connee .tions acomposed of wire rope operatively joined, respectively, to the truck andto the car-body, to permit the truck to swing and accommodate itselftothe maximum curvature of the track, and thereafter serve as stops toprevent further turning of the said trucks, substantially as described.

2. The car-truck and the car-body pivoted thereto, combined with twosets, of flexible connections, a b, composed of wire rope havingattached slotted eyes and extended longitudinally from the truck inopposite directions,and connected,substantiallyas described, to thecar-body and to the corners and sides of the truck, to operate allsubstantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
